Joshua,

Haven't tried this. But my problem would probably not be solved because 
my Windows clients don't care about DNS too much... when they get an IP 
for some name, they stick to it, even if it doesn't answer.  This makes 
it hard to take the server offline for upgrade.

Besides I would like to support secured/authentified SMTP connections in 
the future.  I believe I need a sole entry point to house the SSL 
certificate.
